## Summary description

Fibre optic connector QOLTEC 54187 designed for joining or terminating optical fibers. The product provides a mechanical interface for optical cables, ensuring alignment of fiber cores to enable signal transmission. Suitable for use in fiber optic installations, repairs, patch panels and network extensions where reliable physical coupling of single-mode or multimode fibers is required.

## Long description

Fibre optic connector QOLTEC 54187 is designed for joining or terminating optical fibers, providing a precise mechanical interface that aligns fiber cores to enable reliable signal transmission. The connector supports LC/UPC to LC/UPC coupling in a male-to-female version and is suitable for single-mode and multimode fiber deployments. It is intended for use in fiber optic installations, repairs, patch panels and network extensions where consistent physical coupling and low insertion loss are required.
Advantages
The connector offers accurate core alignment for minimal signal degradation and stable optical performance. Its LC/UPC interface is widely used in telecommunications and data networks, ensuring compatibility with common patch panels and transceivers. The male-to-female configuration simplifies mating and reduces handling stress on fiber ends, while the compact design supports dense rack and panel installations.
Suitable for
Joining or extending optical fiber links in LAN and telecom networks
Repairing or terminating fiber cables in the field or workshop
Connecting patch panels, optical distribution frames and transceivers
Single-mode and multimode fiber applications requiring LC/UPC interfaces
Key specifications
Connector type: LC/UPC to LC/UPC coupling
Configuration: male to female
Fiber compatibility: single-mode and multimode
Interface polarity: UPC polishing for reduced back reflection
Form factor: compact LC footprint suitable for high-density installations
How to use
Before installation, ensure fiber ends are clean and properly cleaved. Align the LC/UPC ferrules of the mating connectors and insert until the latch engages; the male-to-female configuration will provide a secure mechanical connection. Verify optical continuity and measure insertion loss with appropriate test equipment after mating. When disconnecting, gently depress the latch and pull the connector straight out to avoid bending the fiber.
Usage recommendations
Maintain cleanliness of connector end faces by using lint-free wipes and approved fiber cleaning fluids. Store unused connectors with dust caps in place and avoid excessive bending radii at the connector interface. For critical links, perform insertion loss and return loss measurements after installation to confirm performance.
